Surface Water Advisory 
This product may impact surface water quality due to spray drift and run off of rain water. This is especially 
true for poorly draining soils and soils with shallow groundwater. This product is classified as having high 
potential for reaching surface water via runoff for several months after application. A level well maintained 
vegetative buffer strip between areas to which this product is applied and surface water features such as 
ponds, streams, and springs will reduce the potential loading of fomesafen from runoff water and sediment. 
Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 
48 hours. For more information, see the United States Department of Agriculture National Resource 
Conservation Service’s manual, “Conservation Buffers to Reduce Pesticide Losses.” 
 
Non-Target Organism Advisory 
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, 
including pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target 
organisms by following label directions intended to minimize spray drift. 
 
PHYSICAL OR CHEMICAL HAZARDS 
Do not mix or allow coming in contact with oxidizing agents. Hazardous chemical reaction may occur. 
 
DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 
 
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. 
Only protected handlers may be in the area during application. For any requirements specific to your State 
or Tribe, consult the agency responsible for pesticide regulation. 
 
 
PRODUCT INFORMATION 
Read all label directions before using. 
 
AGENT 1.88 is a selective herbicide which may be applied preplant, preemergence or postemergence for 
control or suppression of broadleaf weeds, grasses and sedges in cotton, dry beans, potatoes, snap beans 
and soybeans. 
 
Preplant Surface and Preemergence Applications 
Certain germinating broadleaf weeds, grasses and sedges may be controlled or suppressed by soil residual 
activity from either preplant, preemergent or postemergent applications if rainfall occurs shortly after 
application. The extent and consistency of soil activity is dependent upon soil characteristics, ground cover, 
amount of rainfall following application and the rate of AGENT 1.88 used. 
 
 
 
 
 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR 
part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests, 
nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, 
decontamination, notification, and emergency assistance. It also contains specific instructions and 
exceptions pertaining to the statements on this label about personal protective equipment (PPE), and 
restricted-entry interval. The requirements in this box only apply to uses of this product that are covered 
by the Worker Protection Standard. 
 
Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 24 hours. 
 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and 
that involves contact with anything that has been treated, such as plants, soil, or water, is: 
x Coveralls over short-sleeved shirt and short pants. 
x Chemical-resistant gloves made of bar rier laminate, nitrile rubber, neoprene rubber, or Viton. 
x Chemical-resistant footwear plus socks. 
x Protective eyewear

Postemergence Applications 
AGENT 1.88 is generally most effective and consistent when used postemergence, working through contact 
action. Therefore, emerged weeds must have thorough spray coverage for effective control. 
 
Some bronzing, crinkling or spotting of soybean leaves may occur following a postemergent application, 
but soybeans soon outgrow these effects and develop normally. 
 
Optimum weed control is achieved by postemergent applications of AGENT 1.88 to young actively 
growing broadleaf weeds that are not under stress from moisture, temperature, low soil fertility, 
mechanical or chemical injury. 
 
Soil Characteristics 
Application of AGENT 1.88 to soils with high organic matter and/or high clay content may require higher 
rates than soils with low organic matter and/or low clay content. Refer to the Regional Use Map, weed 
control tables, and specific crop use sections for recommendations on use rates based on soil texture. 
 
Environmental and Agronomic Conditions 
Always apply AGENT 1.88 under favorable environmental conditions that promote active weed growth. 
Avoid applying AGENT 1.88 to weeds or labeled crops which are under stress from drought, extreme 
temperatures, excessive water, low humidity, low soil fertility, mechanical or chemical injury as reduced 
weed control and/or increased crop injury may result. 
 
Rainfastness 
AGENT 1.88 requires a 1 hour rain-free period for best results when applied postemergence. 
 
Cultivation 
Cultivation prior to postemergence application is not recommended. Cultivation may put weeds under 
stress, reducing weed control. Timely cultivation 1-3 weeks after applying AGENT 1.88 may assist weed 
control. 
 
WEED RESISTANCE MANAGEMENT 
For resistance management, 
AGENT 1.88 is a Group 14 herbicide. Any weed population may contain or 
develop plants naturally resistant to AGENT 1.88 and other Group 14 herbicides. Weed species with 
acquired resistance to Group 14 may eventually dominate the weed population if Group 14 herbicides are 
used repeatedly in the same field. Appropriate resistance-management strategies should be followed. 
To delay herbicide resistance, take one or more of the following steps: 
x Rotate the use of AGENT 1.88 or other Group 14 herbicides within a growing season sequence or 
among growing seasons with different herbicide groups that control the same weeds in a field. 
x Use tank mixtures with herbicides from a different group if such use is permitted; where information 
on resistance in target weed species is available, use the less resistance-prone partner at a rate 
that will control the target weed(s) equally as well as the more resistance-prone partner. Consult 
your local extension service or certified crop advisor if you are unsure as to which active ingredient 
is currently less prone to resistance. 
x Adopt an integrated weed-management program for herbicide use that includes scouting and uses 
historical information related to herbicide use and crop rotation, and that considers tillage (or other 
mechanical control methods), cultural (e.g. higher crop seeding rates; precision fertilizer application 
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or 
varieties) and other management practices. 
x Fields should be scouted before application to identify the weed species present and their growth 
stage to determine if the intended application will be effective. Scout after herbicide application to 
monitor weed populations for early signs of resistance development. Indicators of possible 
herbicide resistance include: 
1) failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds; 
2) a spreading patch of non-controlled plants of a particular weed species; 
3) surviving plants mixed with controlled individuals of the same species.

If resistance is suspected, prevent weed seed production in the affected area by an alternative 
Herbicide from a different group or by a mechanical method including hoeing or tillage. Prevent 
movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment 
when moving between fields and planting clean seed. 
x If a weed pest population continues to progress after treatment with this product, discontinue use 
of this product and switch to another management strategy or herbicide with a different mode of 
action (MOA), if available. Treat weed escapes with an herbicide with a different MOA or use non-
chemical methods to remove escapes. To the extent possible do not allow weed escapes to 
produce seeds, roots, or tubers. 
x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC 
representative for pesticide resistance management and/or integrated weed management 
recommendations for specific crops and resistant weed biotypes. 
x For further information or to report suspected resistance, contact your Winfield Solutions, LLC 
representative. 
 
APPLICATION DIRECTIONS 
Application Timing 
Best broad spectrum postemergence control of susceptible broadleaf weeds is obtained when AGENT 
1.88 is applied early to actively growing weeds. This usually occurs 14 to 28 days after planting. Refer to 
the weed control tables for specific recommendations on weed growth stages and rates. 
 
Spray Additives 
Only spray additives cleared for use on growing crops under 40 CFR 180 may be used in the spray mixture. 
 
For best broad spectrum postemergence control of susceptible broadleaf weeds in Regions 2, 3, 4 and 5 
(see Regional Use Maps), AGENT 1.88 should be used with 1.0-2.5% v/v liquid nitrogen (28% or similar) 
or a minimum of 8.5 lbs. ammonium sulfate per 100 gals, of spray volume. 
 
For Postemergence Applications Always Add One of the Following: 
(except in tank mix with products prohibiting spray additives - (See Tank Mix Directions for Use). 
 
Nonionic Surfactant (NIS): 
Use NIS containing at least 80% active ingredient at 0.25 to 0.5% v/v (2-4 qts./100 gals.) of finished spray volume 
(Region 1 and East of Interstates 79 and 77 for Regions 2 and 3). 
 
Crop Oil Concentrate (COC) or Methylated Seed Oil (MSO): 
Use a nonphytotoxic COC or MSO containing 15-20% approved emulsifier at 0.5-1% v/v (2-4 qts./100 gals.) 
of finished spray volume. COC or MSO can improve weed control but may slightly reduce crop tolerance. 
 
Other Adjuvants: 
Adjuvants other than COC or NIS may be used providing the product meets the following criteria: 
1. Contains only EPA exempt ingredients. 
2. Is nonphytotoxic to the target crop. 
3. Is compatible in mixture. (May be established through a jar test.) 
4. Is supported locally for use with AGENT 1.88 on the target crop through proven field trials and 
through university and extension recommendations. 
Note: no adjuvants are needed for preplant or preemergence applications unless AGENT 1.88 is being used 
in a burndown. 
 
Recommended Mixing Order: 
1. Fill spray tank with half the required amount of water and begin agitation* 
2. Add fertilizer (UAN, AMS). 
3. Add dry pesticide formulations. 
4. Add AGENT 1.88. 
5. Add liquid pesticide formulation. 
6. Add adjuvant (MSO, COC or NIS). 
7. Add remainder of water and then maintain constant agitation. 
*Compatibility agent, 1 gal./500 gals, of water or 0.2% v/v, may be added as needed.

Page 6 of 28 
 
 
Tank-Mix Compatibility Test 
A jar test is recommended prior to tank mixing to ensure compatibility of AGENT 1.88 with mixture partners. 
Add proportion amounts of tank mixture components in a clear quart jar one at a time in the recommended 
mixing order. Gently shake or invert capped jar and let stand for 15-30 minutes. If the mixture clumps, 
forms flakes, oily films or layers or other precipitates, it is not compatible and the tank mixture should not 
be used. 
 
Spray Drift Management 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many 
equipment-and-weather-related factors determines the potential for spray drift. The applicator and the 
grower are responsible for considering all these factors when making decisions. 
 
Where states have more stringent regulations, they should be observed. 
 
Mandatory Spray Drift Management 
Ground boom applications: 
x User must only apply with the nozzle height recommended by the manufacturer, but no more 
than 3 feet above the ground or crop canopy. 
x For applications prior to the emergence of crops and target weeds, applicators are required to 
use a Coarse or coarser droplet size in accordance with the most current version of the American 
Society of Agricultural & Biological Engineers Standard 572 (ASAE S572). 
x For all other applications, applicators are required to use a Medium or coarser droplet size in 
accordance with the most current version of the American Society of Agricultural & Biological 
Engineers Standard 572 (ASAE S572). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions. 
Aerial applications: 
x Do not release spray at a height greater than 10 ft. above the vegetative canopy, unless a greater 
application height is necessary for pilot safety. 
x For applications prior to the emergence of crops and target weeds, applicators are required to 
use a Coarse or coarser droplet size in accordance with the most current version of the American 
Society of Agricultural & Biological Engineers Standard 641 (ASABE S641). 
x For all other applications, applicators are required to use a Medium or coarser droplet size in 
accordance with the most current version of the American Society of Agricultural & Biological 
Engineers Standard 641 (ASABE S641). 
x Do not apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater 
than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 
75% or less of the rotor diameter for helicopters. Otherwise, the boom length must be 75% or 
less of the wingspan for fixed wing aircraft and 90% or less of the rotor diameter for helicopters. 
x Applicators must use ½ swath displacement upwind at the downwind edge of the field. 
x Nozzles must be oriented so the spray is directed toward the back of the aircraft. 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
Spray Drift Advisories 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
Importance of Droplet Size 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide 
target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be 
great if applications are made improperly or under unfavorable environmental conditions.

Page 7 of 28 
 Controlling Droplet Size – Ground Boom 
x Volume – Increasing the spray volume so that larger droplets are produced will reduce spray 
drift. Use the highest practical spray volume for the application. If a greater spray volume is 
needed, consider using a nozzle with a higher flow rate. 
x Pressure - Use the lowest spray pressures recommended for the nozzle to produce the target 
spray volume and droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using 
nozzles designed to reduce drift. 
 
 Controlling Droplet Size – Aircraft 
x Adjust Nozzles – Follow the manufacturers recommendations for setting up nozzles. Generally, 
to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. 
 
Boom Height – Ground Boom 
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 
For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
Release Height – Aircraft 
Higher release height increase the potential for spray drift. When applying aerially to crops, do not 
release spray at a height greater than 10 ft above the crop canopy, unless a greater application height 
is necessary for pilot safety. 
 
Shielded Sprayers 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify 
that the shields are not interfering with uniform deposition of the spray on the target area. 
 
Temperature and Humidity 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. 
 
Temperature Inversions 
Drift potential is high during a temperature inversion. Temperature inversions are characterized by 
increasing temperature with altitude and are common on nights with limited cloud cover and light to no 
wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from 
a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a 
concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward 
and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature 
inversions. 
 
Wind 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect 
spray drift. 
 
Sensitive Areas 
The pesticide must only be applied when the potential for drift to adjacent sensitive areas (e.g., 
residential areas, bodies of water, known habitat for threatened or endangered species, nontarget 
crops) is minimal (e.g. when wind is blowing away from the sensitive areas). 
 
GROUND APPLICATION 
See the Spray Drift Management section for spray drift mitigation requirements and advisories 
applicable to ground application. 
 
Preplant Surface and Preemergence Application - Use a minimum of 10 gallons per acre. Nozzle 
selection should meet manufacturer's gallonage and pressure recommendations for preplant surface or 
preemergence applications.

Page 8 of 28 
 
 
 
 
Postemergence Application - Use sufficient spray volume and pressure to ensure complete coverage 
of the target weed. A spray volume of 10-20 gallons per acre and 30-60 psi at the nozzle tip is 
recommended. On large weeds and/or dense foliage, use 60 psi and a minimum of 20 gallons per acre 
to ensure coverage of weed foliage. 
 
The use of flat fan nozzles will result in the most effective postemergence application of AGENT 1.88. 
The sprayer must be calibrated to provide the proper volume and rate per acre. In addition, the boom 
and nozzle height must be adjusted to provide complete coverage of target weeds. 
 
BAND APPLICATIONS 
Thorough weed coverage is important for postemergent control. Best coverage is obtained with a 
minimum of two nozzles, one directed to each side of the planted row. Application with a single nozzle 
directed over the top of the row is not recommended for postemergence applications but is suitable for 
preemergence applications. Cultivation of untreated areas may be needed following band applications. 
When making postemergence band applications and cultivating in the same operation, position nozzles 
in advance of the cultivation device. This will reduce dust in the spray area. Dust can intercept spray, 
reducing weed coverage, resulting in less than adequate weed control. 
 
Calculate the amount of herbicide and water volume needed for postemergence band treatment by the 
following formulas: 
 
Band width in inches X broadcast rate per acre = Band herbicide rate per acre 
Row width in inches 
 
Band width in inches X broadcast volume per acre = Band water volume per acre 
Row width in inches 
 
AERIAL APPLICATION 
See the Spray Drift Management section for spray drift mitigation requirements and advisories 
applicable to aerial application. 
 
Use sufficient spray volume and pressure to ensure complete coverage of the target. A minimum of 5 
gals./A of spray mixture should be applied with a maximum of 40 PSI pressure. When broadleaf weed 
foliage is dense, use a minimum of 10 gals./A to ensure coverage of weed foliage. 
 
DO NOT APPLY THIS PRODUCT THROUGH ANY TYPE OF I RRIGATION SYSTEM, EXCEPT 
CENTER PIVOT SYSTEMS. 
 
CENTER PIVOT IRRIGATION APPLICATION 
AGENT 1.88 alone or in tank mixture with other herbicides on this label, which are registered for center 
pivot application, may be applied in irrigation water preemergence (after planting but before weeds or crop 
emerge) at rates recommended on this label. AGENT 1.88 also may be applied postemergence to the crop 
and preemergence to weeds in crops where postemergence applications are allowed on this label. Follow 
all restrictions (height, timing, rate, etc.) to avoid illegal residues. 
 
Apply this product only through a center pivot irrigation system. Do not apply this product through any other 
type of irrigation system. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can 
result from nonuniform distribution of treated water. If you have questions about calibration, you should 
contact State Extension specialists, equipment manufacturers, or other experts. 
 
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a 
public water system, unless the pesticide label-prescribed safety devices for public water systems are in 
place. A person knowledgeable of the chemigation system and responsible for its operation, or under the 
supervision of the responsible person, shall shut the system down and make necessary adjustments 
should the need arise.

Page 9 of 28 
 
 
Operating Instructions 
x The system must contain a functional check-valve, vacuum relief valve, and low pressure drain 
appropriately located on the irrigation pipeline to prevent water-source contamination from backflow. 
x The pesticide injection pipeline must contain a functional, automatic, quick-closing check-valve to 
prevent the flow of fluid back toward the injection pump. 
x The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated 
valve located on the intake side of the injection pump and connected to the system interlock to 
prevent fluid from being withdrawn from the supply tank when the irrigation system is either 
automatically or manually shut down. 
x The system must contain functional interlocking controls to automatically shut off the pesticide 
injection pump when the water pump motor stops. 
x The irrigation line or water pump must include a functional pressure switch which will stop the water 
pump motor when the water pressure decreases to the point where pesticide distributions adversely 
affected. 
x Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm 
pump or piston pump), effectively designed and constructed of materials that are compatible with 
pesticides and capable of being fitted with a system interlock. 
x Do not apply when wind speed favors drift beyond the area intended for treatment. 
x Prepare a mixture with a minimum of 1 part water to 1 part herbicide(s) and inject this mixture into the 
center pivot system. Injecti ng a larger volume of a more dilute mixture per hour will usually provide 
more accurate calibration of equipment. Maintain sufficient agitation to keep the herbicide in 
suspension. 
x Meter into irrigation water during entire period of water application. 
x Apply in ½ - 1 inch of water. Use the lower water volume (½ inch) on coarser soils and the higher 
volume (1 inch) on fine-textured soils. More than 1 inch of water at application may reduce weed 
control by moving the herbicide below the effective zone in the soil. 
 
Precaution for center pivot applications: Where sprinkler distribution patterns do not overlap 
sufficiently unacceptable weed control may result. Where sprinkler distribution patterns overlap 
excessively, crop injury may result. 
 
Posting of areas to be chemigated is required when 1) any part of a treated area is within 300 feet of 
sensitive areas such as residential areas, labor camps, businesses, day care centers, hospitals, in-
patient clinics, nursing homes or any public areas such as schools, parks, playgrounds, or other public 
facilities not including public roads, or 2) when the chemigated area is open to the public such as golf 
courses or retail greenhouses. 
 
Posting must conform to the following requirements. Treated areas shall be posted with signs at all 
usual points of entry and along likely routes of approach from the listed sensitive area. When there 
are no usual points of entry, signs must be posted in the corners of the treated areas and in any other 
locations affording maximum visibility to sensitive areas. The printed side of the sign should face away 
from the treated area towards the sensitive area. The signs shall be printed in English. Signs must be 
posted prior to application and must remain posted until foliage has dried and soil surface water has 
disappeared. 
Signs may remain in place indefinitely as long as they are composed of materials to prevent 
deterioration and maintain legibility for the duration of the posting period. 
 
All words shall consist of letters at least 2.5 inches tall, and all letters and the symbol shall be a color 
which sharply contrasts with their immediate background. At the top of the sign shall be the words 
KEEP OUT, followed by an octagonal stop sign symbol at least 8 inches in diameter containing the 
word STOP. Below the symbol shall be the words PESTICIDES IN IRRIGATION WATER. 
 
Posting required for chemigation does not replace other posting and reentry interval requirements for 
farm worker safety.

Specific Instructions for Public Water Systems 
1. Public water system means a system for the provision to the public of piped water for human 
consumption if such system has at least 15 service connections or regularly serves an average of 
at least 25 individuals daily at least 60 days out of the year. 
2. Chemigation systems connected to public water systems must contain a functional, reduced-
pressure zone, back-flow preventer (RPZ) or the functional equivalent in the water supply line 
upstream from the point of pesticide introduction. As an option to the RPZ, the water from the public 
water system should be discharged into a reservoir tank prior to pesticide introduction. There shall 
be a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow 
rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 
3. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to 
prevent the flow of fluid back toward the injection pump. 
4. The pesticide injection pipeline must contain a functional, normally closed, solenoid-operated valve 
located on the intake side of the injection pump and connected to the system interlock to prevent 
fluid from being withdrawn from the supply tank when the irrigation system is either automatically 
or manually shut down. 
5. The system must contain functional interlocking controls to automatically shut off the pesticide 
injection pump when the water pump motor stops, or in cases where there is no water pump, when 
the water pressure decreases to the point where pesticide distribution is adversely affected. 
6. Systems must use a metering pump, such as a positive displacement injection pump (e.g., 
diaphragm pump) effectively designed and constructed of materials that are compatible with 
pesticides and capable of being fitted with a system interlock. 
7. Do not apply when wind speed favors drift beyond the area intended for treatment. 
 
USE PRECAUTIONS 
x Thoroughly clean the spray system with water and a commercial tank cleaner before and after each 
use. 
x Tank mixes of AGENT 1.88 with other pesticides, fertilizers or any other additives except as specified 
on this label or other approved Winfield Solutions, LLC supplemental labels may result in tank mix 
incompatibility, unsatisfactory performance and/or unsatisfactory crop injury. 
x Apply postemergence to actively growing weeds. Avoid applying AGENT 1.88 to weeds or soybeans 
which are under stress from moisture, temperature, low soil fertility, mechanical or chemical injury, 
as reduced weed control and/or increased crop injury may result. 
x Avoid overlapping spray swaths, as injury may occur to rotational crops. 
 
USE RESTRICTIONS 
x Do not apply more than 1.6 pts. of AGENT 1.88 (or a maximum of 0.375 lbs. a.i./A of fomesafen 
from any product containing fomesafen) per acre per year in Region 1 (see Regional Use Map) 
x Do not apply more than 1.6 pts. of AGENT 1.88 (or a maximum of 0.375 lbs. a.i./A of fomesafen 
from any product containing fomesafen) per acre in alternate years in Region 2 (see Regional Map). 
x Do not apply more than 1.3 pts. of AGENT 1.88 (or a maximum of 0.313 lbs. a.i./A of fomesafen 
from any product containing fomesafen) per acre in alternate years in Region 3 (see Regional Map). 
x Do not apply more than 1 pt. of AGENT 1.88 (or a maximum of 0.25 lbs. a.i./A of fomesafen from 
any product containing fomesafen) per acre in alternate years in Region 4 (see Regional Map). 
x Do not apply more than 0.75 pt. of AGENT 1.88 (or a maximum of 0.1875 lbs. a.i./A of fomesafen 
from any product containing fomesafen) per acre in alternate years in Region 5 (see Regional Map). 
x Do not graze treated areas or harvest for forage or hay. 
x Do not apply within 45 days of soybean harvest. 
x To provide adequate spray coverage, ground speed must not exceed 10 MPH during application. 
 
Replanting: 
If replanting is necessary in fields previously treated with AGENT 1.88, the field may be replanted to 
cotton, dry beans, potatoes, snap beans or soybeans. During replanting, a minimum of tillage is 
recommended to preserve the herbicide barrier for effective weed control. Do not apply a second 
application of AGENT 1.88 or other fomesafen-containing product as crop injury or illegal residues may 
occur in harvested crops. If tank-mix combinations were used, refer to product labels for any additional 
replanting instructions.

Partial Control* of Perennial Weeds: 
Use of AGENT 1.88 at postemergence rates of 1 - 1.6 pts./A will aid in suppressing the above-ground 
portions of the weeds listed below until crop canopy can assist in suppression. Perennial weeds continue 
to regrow from underground rootstocks even if above-ground foliage is temporarily controlled or retarded.

Page 20 of 28 
 
 
Even though AGENT 1.88 and crop competition can suppress perennial weeds for a growing season, the 
rootstocks will continue to live and reestablishment will occur in subsequent years.

COTTON USE DIRECTIONS 
Preemergence Application: 
Apply Agent 1.88 pre-emergence at 1 - 1.6 pts./A in cotton in Region 1 for control or partial control of the 
weeds listed in Table 1 of the container label. Apply as a pre-emergence treatment only to coarse textured 
soils (sandy loam, loamy sand, sandy clay loam). 
 
Do not apply as a pre-emergence treatment to medium or fine-textured soils as crop injury will likely 
occur. 
 
To broaden the weed control spectrum, Agent 1.88 may be tank mixed with other preemergence herbicides 
such as Caparol®, Cotoran®, Direx®, Karmex®, Solicam®, or Staple®. 
 
For control of emerged weeds, Agent 1.88 may be tank mixed with a burndown herbicide such as 
Gramoxone Inteon™ or glyphosate brands (such as Touchdown®, Roundup®) labeled in cotton. In 
reduced tillage plantings, Agent 1.88 can be applied up to 14 days prior to planting or at planting with a 
burndown herbicide. Refer to the tank-mix partner label for use directions, restrictions and limitations. The 
most restrictive product labeling applies. 
 
Cotton plants are tolerant to pre-emergence applications of Agent 1.88 when applied at recommended 
rates and to coarse textured soil types. Some crinkling or spotting of cotton foliage or stunting may occur, 
especially if heavy rainfall occurs during or soon after cotton emergence, but cotton plants normally outgrow 
these effects and develop normally. 
 
Cotton foliage is not tolerant to Agent 1.88. Do not apply Agent 1.88 over the top of emerged cotton as 
unacceptable cotton injury will occur. 
 
Post-Directed Application: 
Apply Agent 1.88 in emerged cotton as a post-directed treatment using precision post-directed, hooded or 
shielded application equipment to provide complete coverage of emerged weeds. Apply Agent 1.88 at 1 - 
1.6 pints per acre in a minimum of 10 gallons spray solution per acre. 
 
Post-directed applications of Agent 1.88 will provide contact control of labeled emerged weeds and residual 
pre-emergence control of labeled weeds (once activated by rainfall or irrigation). See container label 
sections for a list of weeds controlled, recommended application rates, weed growth stages, and 
application directions. 
Agent 1.88 should be applied with a non-ionic surfactant at 0.25 to 0.5% v/v, or crop oil concentrate at 1% 
v/v to emerged weeds. Do not add liquid nitrogen (28% or similar) to Agent 1.88, or Agent 1.88 tank mixes 
in cotton. 
 
To broaden the weed control spectrum, post-directed applications of Agent 1.88 may be tank mixed with 
other labeled post-directed herbicides such as Caparol, Direx, Dual MAGNUM®, Envoke®, Karmex, 
Layby™ Pro, Sequence®, or Suprend®. When applied with hooded or shielded sprayers, Agent 1.88 and 
Agent 1.88 tank mixes may be applied with burndown products such as Gramoxone Inteon, Sequence or 
glyphosate brands (such as Touchdown, Roundup) labeled for in crop application in cotton. Refer to the 
tank-mix partner label for use directions, restrictions and limitations. The most restrictive product labeling 
applies.

Page 21 of 28 
 
Cotton foliage is not tolerant to Agent 1.88 applications. Avoid contact to cotton foliage as unacceptable 
injury will occur. Application equipment should be calibrated (spray pressure, nozzle type and configuration, 
and orifice size) to avoid fine spray droplets contacting green cotton stems and foliage. 
 
Post-Directed Application Timing In Cotton: 
Agent 1.88 may be applied to cotton at least 6 inches in height through lay-by as a post-directed application. 
All post-directed applications should avoid spray contact with any green non-barked parts of the cotton plant 
or foliage as unacceptable injury will occur. Follow the application timing recommendations below for post-
directed applications in cotton. 
 
Shield And Hooded Applications: 
Make a precision post-directed Agent 1.88 application to the base of the cotton plant avoiding contact 
with the cotton stem or foliage when cotton is at least 6 inches in height to avoid cotton injury. Use only 
hooded or shielded spray equipment to apply Agent 1.88 in cotton that is 6 inches to 12 inches in height. 
Adjust nozzles to provide full coverage of emerged target weeds. 
 
Layby Applications: 
Make a post-directed AGENT 1.88 application to the base of the cotton plant avoiding contact with any 
non-barked portion of the cotton plant or foliage. Use precision post-directed equipment or hooded or 
shielded sprayers on cotton that has developed a minimum of 4 inches of brown bark through layby. 
Application equipment should be configured to provide full coverage of emerged target weeds. 
 
RESTRICTIONS FOR USE ON COTTON: 
x Do not apply Agent 1.88 later than 70 days before harvest. 
x Do not apply more than 1.6 pints per acre of Agent 1.88 in any year. 
x Do not make more than one application of Agent 1.88 per year. 
x If two consecutive year applications are made, allow a 2 year interval before another application. 
 
Special Use Directions for the Suppression of Woollyleaf Bursage (Lakeweed), Ambrosia gray/, in 
Texas: 
Apply Agent 1.88 to cultivated areas of cropland in the fall or spring as a spot treatment at a rate of 1.6 
pints per acre and incorporate to a depth of 2-3 inches for suppression of woollyleaf bursage. 
Applications should be made with ground equipment. 
 
The use of adjuvants, as specified under the Spray Additives section, will significantly improve the initial 
burndown of any emerged woollyleaf bursage, but this effect is only temporary. Therefore, an adjuvant 
may be used if desired, but is not necessary. 
 
Significant suppression may not be seen until 6-8 months after application, but should then continue for 
at least 2 years after application. Cotton or soybeans may be planted in treated areas. Under certain 
conditions, significant damage may occur to cotton planted within 18 months of application. A 3-year 
interval from last application to planting is required for all other crops. 
 
DRY BEANS AND SNAP BEANS 
Preplant Surface and Preemergence Application 
Apply AGENT 1.88 as a preplant surface or preemergence application in Regions 1 , 2, 3, and 4 only for 
control or partial control of the weeds listed in Table 1. AGENT 1.88 can be applied alone, or tank mixed 
or followed sequentially with other labeled dry bean or snap bean herbicides to broaden the weed control 
spectrum or control newly emerged weeds. Refer to the Tank Mix and Sequential Application section for 
additional information. 
 
NOTE: Treated soil that is splashed onto newly emerged seedings may result in temporary crop injury but 
plants normally outgrow these effects and develop normally.

Page 22 of 28 
 
 
Postemergence Application 
Apply AGENT 1.88 as a postemergent broadcast application in Regions 1 , 2, 3, 4 and 5 for control or 
partial control of the weeds listed in Table 2 and in the Special Use Directions for Additional Weed Problems 
section. Application rate depends on weed species and growth stage. Two applications may be made if 
necessary but not to exceed the maximum rate specified per geographic region. (Refer to map for definition 
of specified geographic regions). Refer to the Spray Additive section for recommended spray additives. 
Use of crop oil concentrate can improve weed control but may slightly reduce crop tolerance. 
Do not use UAN (28% or similar) or ammonium sulfate on dry beans or snap beans as severe crop injury 
may occur. Apply when dry beans or snap beans have at least one fully expanded trifoliate leaf. 
 
AGENT 1.88 can be applied alone or in tank mix with other labeled dry bean or snap bean postemergence 
herbicides to broaden the weed control spectrum. Refer to the Tank Mix and Sequential Application section. 
 
Some bronzing, crinkling or spotting of dry bean or snap bean leaves may occur following postemergent 
applications, but dry beans and snap beans soon outgrow these effects and develop normally. 
 
Tank Mix and Sequential Applications for Dry Beans and Snap Beans 
 
AGENT 1.88 can be used sequentially or in tank mix with the following products: 
 
Dry Beans and Snap Beans Dry Beans Only 
Assure II® Frontier® 
Basagran® Clethodim 2E 
Dual MAGNUM Sonalan® 
Eptam® 
Poast® 
Prowl® 
Imazethapyr 2SC 
Raptor® 
Trifluralin 4E 
 
Under certain conditions, the mixture of AGENT 1.88 with one or more of the above mentioned broadleaf 
herbicides may cause a reduction in activity of any post-emergence grass herbicide in the mixture. 
 
For sequential applications allow 2-3 days after the application of the post-emergence grass herbicide 
before applying AGENT 1.88 or AGENT 1.88 mixtures. Where AGENT 1.88 or the AGENT 1.88 mixture is 
applied first, apply the grass herbicide when the grass weeds begin to develop new leaves (generally around 
7 days). 
 
NOTE: Tank-mix applications can result in increased crop injury as compared to either product used alone. 
 
Always read and follow the recommendations, restrictions and limitations for all products whether used 
alone, sequentially or in a tank mix. The most restrictive labeling of any product used applies. 
 
Restrictions - Dry Beans and Snap Beans 
x Refer to AGENT 1.88 Regional Use Map for the maximum rate of AGENT 1.88 (or other fomesafen 
containing products) that may be applied in each geographic region. 
x Do not apply to any field in Regions 2, 3, 4 or 5 more than once every two years. 
x For snap beans: Do not exceed 1.6 pints of AGENT 1.88 per acre in any one year and also adhere

SOYBEANS 
Preplant Surface and Preemergence Application 
Apply AGENT 1.88 as a preplant surface or preemergence application in Regions 1, 2, 3, and 4 only for 
control or partial control of the weeds listed in Table 1. AGENT 1.88 can be applied alone or tank mixed or 
followed sequentially with other labeled soybean herbicides to broaden the weed control spectrum or 
control newly emerged weeds. Refer to the Tank Mix and Sequential Application section for additional 
information. 
 
For control of emerged weeds, AGENT 1.88 may be tank mixed with a burndown herbicide such as 
Gramoxone Inteon or glyphosate brands (such as Touchdown or Roundup) labeled in soybeans. In reduced 
tillage plantings, AGENT 1.88 can be applied up to 14 days prior to planting or at planting with a burndown 
herbicide. 
 
Postemergence Application 
Apply AGENT 1.88 as a postemergence broadcast application in Regions 1, 2, 3, 4 and 5 for control or 
partial control of weeds listed in Table 2 and in the Special Use Directions For Additional Weed Problems 
section. Application rate depends on weed species and growth stage. Refer to the Spray Additive section 
for recommended spray additives. To enhance postemergence control of susceptible broadleaf weeds 
(soybeans only) in Regions 2, 3, 4 and 5 (see Regional Use Map), AGENT 1.88 can be used with a 
minimum of 2.5% liquid nitrogen (28% or similar) or a minimum of 10 pounds ammonium sulfate per 100 
gallons of spray volume. 
 
AGENT 1.88 can be applied alone or in combination with other labeled soybean postemergence herbicides 
to broaden the weed control spectrum. Refer to the Tank Mix and Sequential Application section. 
 
Some bronzing, crinkling or spotting of soybean leaves may occur following postemergent applications, 
but soybeans soon outgrow these effects and develop normally.

TANK MIX AND SEQUENTIAL APPLICATIONS FOR SOYBEANS 
AGENT 1.88 can be used sequentially or in tank mix with one or more of the following products: Assure 
II®, Basagran®, Butyrac®, Classic®, FirstRate®, Fusilade DX, Fusion, Ignite®, Glyphosate (such as 
Touchdown®, Roundup®, Glyphomax™, Gramoxone® Inteon, Harmony®, Poast®, Poast Plus®, 
Pursuit®, Raptor®, Resource®, Scepter®, Select®, and Synchrony® STS®. 
 
Under certain conditions, the mixture of AGENT 1.88 with one or more of the above mentioned broadleaf 
herbicides may cause a reduction in activity of any postemergence grass herbicide in the mixture. 
 
For sequential applications allow 2-3 days after the application of the grass herbicide before applying 
AGENT 1.88 or AGENT 1.88 mixtures. Where AGENT 1.88 or the AGENT 1.88 mixture is applied first, 
apply the grass herbicide when grass weeds begin to develop new leaves (generally around 7 days). 
 
x Tank mix applications can result in increased crop injury as compared to either product used alone. 
x Do not exceed 1 fl. oz. of Butyrac per acre in mixture with AGENT 1.88. 
x Do not exceed 0.25 oz./A of Synchrony STS herbicide in the tank with labeled rates of AGENT 1.88 
on non-STS varieties. This tank mix can be applied postemergence to any soybean variety for 
additional broadleaf weed control. Refer to the Synchrony STS label for more information and crop 
rotation restrictions. 
x Always read and follow the directions, restrictions and limitations for all products whether used alone, 
sequentially or in a tank mix. The most restrictive labeling of any product used applies. 
 
GLYPHOSATE TOLERANT SOYBEAN TANK MIXES 
AGENT 1.88 at 6-12 oz./A, can be tank mixed with glyphosate products (such as Touchdown or Roundup) 
that are labeled for glyphosate tolerant soybeans for improved postemergence control of many weeds 
such as morning-glory spp., hemp sesbania, waterhemp, and black nightshade which are known to have 
tolerance to glyphosate, but are susceptible to AGENT 1.88. 
 
FOLLOW THE RECOMMENDATIONS ON THE GLYP HOSATE PRODUCT LABEL FOR THE USE OF 
SPRAY ADDITIVES IN THIS TANK MIX. 
 
Do not allow this tank mix to move off target as contact by even minute quantities can cause severe 
damage or death to any non-target vegetation. 
 
Note: Postemergence application of this tank mix on soybean varieties which do not contain the 
glyphosate tolerant gene will result in severe crop injury or death of the soybean crop. Always read and 
follow the recommendations, restrictions and limitations for all products used. The most restrictive labeling 
of any product applies. 
 
Product Use Restrictions – Soybeans 
Refer to Regional Use Map for the maximum rate of AGENT 1.88 (or other fomesafen containing products) 
that may be applied in each geographic region. Do not apply to any field in Region 2, 3, 4 or 5 more than 
once every two years. 
 
Do not exceed 1.6 pints of AGENT 1.88 per acre in one year and also adhere to the maximum rate that 
may be applied in each geographic region (refer to the Regional Use Map). 
 
Do not graze treated areas or harvest for forage or hay. 
Do not apply within 45 days of harvest.
